Answer 1

Answer:

${ 11 = 3 {311? \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} }^{2} 2$

Answer 2

❏ Used ForMuLaS:-

If $\alpha \:and \:\beta$ are two zeroes of the quadratic equation

➔ ax²+bf+c=0

And,the equation holding the sum and the product of the zeroes is given by,

➔$\bf \sf\boxed{x{}^{2}-(\alpha+\beta)x+\alpha \beta=0}$

❏ Question:-

Q) If m and n are two zeroes of the quadratic equation ➝ x²+x+1=0

Then find $\sf\longrightarrow \frac{1}{m}+\frac{1}{n}$= ?

❏ Solution:-

❚➾

Now, x²+x+1=0

➝x²+(-1)x+1=0.......(i)

Now comparing the equation (i) with the equation $\bf \sf x{}^{2}-(m+n)x+mn=0$

we get,

➔ (m+n)=(-1)

and ,

➔ mn=1

Now,

$\sf\longrightarrow \frac{1}{m}+\frac{1}{n}$

$\sf\longrightarrow \frac{m+n}{mn}$

[ putting the values m+n=-1 and mn=1 ]

$\sf\longrightarrow \frac{-1}{1}$

$\sf\longrightarrow \boxed{\large{\red{-1}}}$
